# This adds a special type of git repository, where the .git directory
# is stored on a file server, to avoid wasting space with it on the client.
# One example use is storing a music collection in git, where you can spare
# the extra space needed for .git on your file server, but not on your
# laptop. This fills basically the same niche as unison.
# 
# To make mr use this file, add a line like this inside the [DEFAULT]
# section of your ~/.mrconfig
#include = cat /usr/share/mr/git-remote
#
# And an example repo using it would look something like:
#[lib/sound]
#checkout = git_remote_checkout turtle /media/turtle/home/joey/lib sound
# 
# In this example, the file server's hostname is "turtle", 
# and it's mounted on /media/turtle. The file server contains a sound.git
# repository in the specified directory under that mount point.
# When mr checks out that repository, it will create a sound.hostname
# directory on the server, containing just the .git directory, and symlink
# the client's .git directory to it. After checkout, normal git and mr
# commands can be used, as long as the file server is available.
